Definitions

  • a widely adopted method to improve handling stability, particularly road gripping properties, is to increase the hysteresis loss of tread rubber compositions.
  • a large hysteresis loss during the deformation of tread is used for increasing a friction force between the tread and road surface.
  • a significant increase of heat buildup will occur during the running of the tires as the hysteresis loss of the tread rubber becomes large, causing wear resistance of the tread rubber to deteriorate rapidly.
  • vehicle controllability is significantly influenced by hardness (which is closely related to cornering stiffness of a tire) and breaking strength of rubber compositions.
  • JP-A- 2005/350535 , WO-A- 2007/026707 , US-A-, 5,284,907 , US-A-2003/080,681 , US-A- 2003/220,428 and US-A- 2004/072,934 describe various rubber compositions and tires made with such rubber compositions comprising diene based elastomers and plasticizers.
